Which component is not included in a box-and-whisker plot?

In a box-and-whisker plot, the primary components include the minimum value (or lower extreme), the lower quartile (Q1), the median (Q2), the upper quartile (Q3), and the maximum value (or upper extreme). The purpose of a box-and-whisker plot is to represent the distribution of a data set, highlighting its central tendency and variability.

The mean, on the other hand, is the average of all data points and is not inherently represented in this type of plot. While the mean provides useful information about the data set, it does not fit into the structure of a box-and-whisker plot, which focuses on quartiles and extremes rather than on computing averages. Therefore, the correct response identifies that the mean is the component that is not included in the box-and-whisker plot.
